G RAVlTYr'BAT-TERY.

SPECIFICATION forming part of Letters Patent No. 712,668, dated November4, 1902.

Application filed January 16, 1902. Serial No. 90,086. (No model.)

To LtZZ whom, it may concern:

Be it known that I, \VILFRED N. GOVE, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inGravity- Batteries; and I do declare the following to bea full, clear,and exactdescription of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The invention relates to a gravity-battery. The object of the inventionis to provide a battery of this character of high power and of greatdurability.

The invention consists particularly in the substitution for the copperelement usually employed in batteries of this character of an elementcomposed solely of Babbitt metal, which by experiment has beendemonstrated to materially increase the strength of the battery andwhich is not so susceptible of decomposition as the copper now sogenerally used.

In the accompanying drawings, Figure 1 is a perspective view of abattery embodying my invention. Fig. 2 is a longitudinal verticalsectional View. Fig. 3 is a View of the Babbitt-metal element of thebattery.

Referring now more particularly to the drawings, the numeral 1represents the cell of the battery; 2, the blue-stone; 3, the zinc; 4:,the solution, and'5 the Babbitt-metal element of the battery. Thiselement 5 of the battery is preferably made in the form of a plate ofany suitable dimensions and outlines and is arranged in the cell in ahorizontal plane, so that instead of having its edges attacked and' theconsequent decomposition of metal at these points the decomposition isgradual upon the surface of the plate and is hardly noticeable untilafter several months usage of the battery. It is believed that thisresult is attained by the employment of: the alloy Babbitt metal, and ithas been demonstrated in'practice that one jar or cell containingBabbitt metal as one of the elements of the battery isequal in strengthto two jars or cells in series in which copperis employed as one of theelements of the battery.

Each cell of my improved battery has an electromotive force of 1.20volts, and it has been found that one cell was capable of furnishingsufficient electromotive force to work afour-ohm-resistance telegraphicsounder.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, mode of operation, andadvantages of my improved battery will, it is thought, be readilyapparent without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is-- 1. Babbitt metal as an element of abattery.

2. A gravity-battery composed of a solution, blue-stone, zinc andBabbitt metal.

3. Agravity-battery composed of a solution, blue-stone, zinc, andBabbitt metal, said Babbitt metal being in the form of a plate thesurface of which is parallel with that of the solution.

4. A plate of Babbitt metal as an element of a battery.

5. A plate of Babbitt metal arranged in a horizontal plane, as anelement of a gravitybattery.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. 1

WILFRED N. GOVE.
